CLOSURE FOR HOT-WATER BAGS OR BOTTLE-S.

Specification of Letters Patent.

Patented Sept. 19, 15916.

Application filed November 24, 1915. Serial No. 63,213.

To all whom it m rig concern:

Be it known that I, Osras M. 'GOT'rEsMAN, a prior subject of the King of Roumania, having declared my intention of becoming an American citizen, residing at New York, in the borough of Manhattan and State of New York, have invented certain new and useful Improvements in Closures for Hotiiater Bags or Bottles, of which the following is a specification.

My invention relates to closures for hot water bags or bottles, and has for its objects to provide an improved construction of the same, whereby an effective sealing of the bag or bottle may be effected, and at the same time the closure member will, when unsealed or opened, be retained in its relation to the bag or bottle, so as to be ready at all times for use. These objects I accomplish in the manner and by the means hereinafter described and claimed, reference being had to the accompanying drawing, in which Figure 1 is a vertical sectional view of the upper portion of a water bag or bottle embodying my improved construction. Fig. 2 is a top plan view of the neck of the same. Fig. 3 is a horizontal sectional view taken on the line IIl-HI of Fig. 1. Fig. at is a detail vertical sectional view of the closure and its sleeve, the closure being shown in sealing position. Fig. 5 is a view similar to t, except that the closure is shown in full lines, and is shown in the open position. Fig. 6 is a view similar to Fig. a, illustrating a modified construction. Fig. T is a top plan view of the valve casing shown in Fig. (3, the valve stem being omitted.

Similar numerals of reference denote corresponding parts in the several views.

In the said drawing, the reference numeral 1. denotes a conventional water bag or bottle, preferably formed of rubber, and provided with an integral neck 2, the same being extended into a filling funnel 8 of the usual construction. Disposed in the neck 2 0f the bag or bottle is a valve casing 4, the same being retained tightly in place preferably by means of a layer 5 of rubber Cement, the exterior surface of said casing being corrugated, as shown, in order to more firmly be grasped by the inner surface of the neck 2. The lower end of said casing is constricted annularly to form a valve seat 6, as hereinafter described.

Disposed centrally within the'valve casing 4 is a sleeve 7, the same being connected integrally to the valve casing 4,- by means of spider arms 8. Said sleeve 7 is slotted vertically on one side at 9, said slot mor ing into a horizontally disposed slot 10 at its lower end. The upper edge of said sleeve to one side of the vertical slot 9 is formed at an angle to provide a cam surface 11, and on its other side is provided with an upstanding lip or stop 12. l jitting within said sleeve 7 is a valve stem 13, carrying a suitable valve 1% at its-lower end, said valve preferably being provided with a rubber packing 15 to engage the annular valve seat (3 when in closed position to form a water tight closure. Projecting from one side of said valve stem 13 is a pin 16, which is adapted to move in the vertical slot 9, and, when registering with the horizontal slot 10, to move therein when the valve stem 13 is rotated horizontally. The said pin is also adapted when lifted to engage the cam sur fac 11 at the top of the sleeve 7, the two giving a cam action to said stem and to its valve 14, as readily will be understood.

In operation, when the valve stem 13 is in the position shown in Fig. 5, the valve is wide open and the pin 16 is turned into the horizontal slot 10, thereby preventing accidental elosing movement to the valve when the bag or bottle is inverted to empty the same. In order to close the valve, the same is rotated until the pin 16 registers with the vertical slot 9 when said stem may be raised bodily. which raises the valve 14- into contact with the valve seat 6. This movement brings the pin 16 in alincment with the upper cam surface 11 of the sleeve 7, and upon rotating the stem 13 to the right, said sur face acts on said. pin as a cam to force the valve 14 tightly against the valve seat 6, whereby a perfect closure is obtained. The stop 12 will prevent the pin 16 from regis tering with the slot 9 when turned too far to the right, and will require a movement of said stem 13 to the left in order to open the valve.

in the modification shown in Figs. 6 and 7, the principle of operation disclosed in the remaining figures is retained, but the pin 16 moves in either one of two slots 9 on the interior of the sleeve 7, said slots not extending entirely through the sleeve. Said pin 16 when in its lowermost position is turned by the shaft 13 beneath the bottom surface of the sleeve 7 indicated at 7".

Furthermore, the construction of the stopper proper is slightly different, the stem 13 being provided with a shoulder 17 against which the upper plate 18 of the stopper abuts to limit the movement of the latter. Between said plate 18 and an underlying disk 19 is a thin disk 20 of soft material, such as rubber, said disk 19 being freely movable on the reduced lower end of the stem 13 and being pressed upwardly against the plate 18 by a spring washer 21, which is retained in position upon the stem by a cotter pin 2 The result of this construction is that when the valve is brought to closed position against its seat and the stem 13 is rotated to cause the pin 16 to ride over the eammed upper surface of the sleeve 7, the resilient disk 20 of the stopper will contact with the valve seat and will be pressed yieldto position by the spring washer 21.

ing thus described my invention, what I claim as new and desire to secure by Lettors Patent, is

l. A closure for water bottles, comprising a valve seat in the bottle neck, a sleeve centrally disposed with respect to said seat and in fixed relation thereto, an inwardly opening valve for said seat, a valve stem therefor passing through and freely movable in said sleeve, and a pin on said valve stem movable in a longitudinal slot in said sleeve and adapted to engage a cam surface on said sleeve upon the rotation of one of the parts to force said valve to closed position against said seat.

A closure for water bottles, comprising a valve seat in the bottle neck, a sleeve centrally disposed with respect to said seat and in fixed relation thereto, an inwardly opening valve for said seat, a valve stem therefor passing through and freely movable in said sleeve, and a pin on said valve stem movable in a longitudinal slot in said sleeve and adapted, upon rotation of one of the parts, to lock said valve in either its open or its closed position.

a valve seat in the bottle neck, a sleeve centrally disposed with respect to said seat and in fixed relation thereto, a valve stem passing through said sleeve, an inwardly opening valve on said' valve stem, and a spring on said valve stem engaging said valve and normally forcing the same toward its seat.

i. A closure for water bottles, comprising 0. A closure for water bottles, comprising a valve seat in the bottle neck, a sleeve centrally disposed with respect to said seat and in fixed relation thereto, an inwardly opening valve for said seat, a valve stem therefor passing through said sleeve, a pin on said valve stem movable in a longitudinal slot in. said sleeve and adapted to engage a cam surface on said sleeve upon therotation of one of the parts to force said valve to closed position against said seat, and a spring engaging said valve and normally forcing the same toward its seat.

5. A closure for water bottles, comprising a valve seat in the bottle neck, a sleeve centrally deposed with respect to said seat and in fixed relation thereto and provided with a longitudinal slot, a valve stem passing through said sleeve, an inwardly opening valve for said seat slidable on said stem and limited. in its movement in one direction by a shoulder on said stem, a pin on. said stem adapted to move in said slot and to engage a cam surface at the outer end of said sleeve upon the rotation of said stem to force said valve to closed position. against said seat, and a spring washer mounted on said stem beneath said valve and adapted to yieldingly hold the same against the shoulder on said stem.

6. A closure for water bottles, comprising a valve seat in the bottle neck, a sleeve centrally disposed with respect to said seat and in fixed relation thereto and provided. with a longitudinal. slot, a valve stem passing through said sleeve, an inwardly opening valve for said seat slidable and rotatable on said stem and limited in its movement in one direction by a shoulder on said stem, a resilient disk on said valve forming the seating surface, a pin on said stein adapted to move in the slot in the sleeve and to engage a cam surface at the outer end of said sleeve pen the rotation of said stem to force said valve to closed position against said seat, and a spring washer mounted on said. stein beneath said valve adapted to yieldingly hold the same against the shoulder on said stem, said valve and its resilient disk being retained by the frictional contact with the valve seat against rotation during this 0P? oration.

In testimony whereof I have hereuntoset my hand this 3rd day .of November, 1915.
